Abstract:

Under the assumption of the two-user Gaussian interference channels with a single Gaussian codebook, no power control and no significant coordination between the transmitters, a decoding strategy is proposed to achieve the best rate region or sum rate according to the channel gains and power parameters. The proposed decoding strategy exploits two fundamental decoding methods and is described in two equivalent forms of channel parameters, which shows that the best decoding strategy is not determined by the intensity of the channel gains but depends on both channel gains and power parameters.

Key words: interference channel, Gaussian interference channel, decoding strategy, achievable rate region, sum rate
